In this video, we will tell you a very brief review of our research progress in the last two weeks,

First, after further consultation with our professor of electronics and fisheries, and also after we collaborated with the field experts, We’re able to finalized the design of the new concept of Mino that have several additional support system such as bio floc, control system for the dissolved oxygen, and solar cell.

In this design, we will add Biofloc in the inlet section of MINO.

Biofloc is a protein rich aggregate of organic material and micro-organisms such as bacteria, protozoa and algae that have a lot of benefits.

a. Biofloc is protein rich and highly digestible for tilapia.

b. It is environmentally friendly which has Low water consumption, able to increase biosecurity, and little/no release of inorganic pollutants (Nitrogen and Phosphorus)

c. Its also very easy to obtained and inexpensive by-products

Then, we will add the dissolved oxygen sensor to regulate oxygen levels. That dissolved oxygen sensor will calculate the amount of oxygen in the pond. If the dissolved oxygen levels in the pond detected as low, the sensor will give information to microcontroller.

In the microcontroller, the data from the dissolved oxygen sensor will be processed with arithmetic and logic methods; the operating logic, sequential, timers, counters.

Results of data processed by the Microprocessor will be issued in digital signals to run the actuator, or if its in this system: our pump. And it will work vice versa, when the dissolved oxygen level is high, then the system will make the pump off automatically.

The system is designed to make the pump work more effective and efficient, Furthermore, this system will save the consumption of electricity used.

Then, we designed the solar cell system as the electrical source for MINO. This solar cell will gather the solar energy and converted to DC Current. The current will be saved in Accumulator. DC Current will be converted to AC current 220 volt with the inverter to turn on the pump

Secondly, we did a lab test with our new design of the main section of Microbubble Generator that we’ve talked about in the last video. Based on the product design theory, we designed the new model that is more simple, easy and efficient for fabrication.

This new model, will be more easy to fabricate compared to the previous model, in this new model we tried to minimize the design by minimizing the number of joints and whorls, thus it will be easier to fabricate, less time consuming and cheaper to fabricate.

To check the effectivity of this new model, we did the lab test to see if this new model will generate the same or even smaller size of Microbubble.

Beside of doing visual observation to determine the bubble size, we also tried to validate it by using High Speed camera to capture the image of the bubble, the result will be processed with the matlab program, so we will get the information of the actual size of the bubble produced.

Visually speaking, this design was able to generate a really good size of microbubble. This research has been supported by laboratorium of fluid mechanics, mechanincal and industrial engineering department and center of energy studies UGM

For this weekend,

We will conduct deep interview with the fish farmers of Bokesan Yogyakarta to see whether our technology and our pricing range are suitable with their needs and also we will held socialization about aquaculture and technology to the fish farmers group.

Other than the progress we’ve mentioned before, We also have started to discuss closely with our mentor and will prepare the best way to pitch our idea.

Untukmu,

Yang berpaling, bahkan sebelum langkah kita sempat beriring

Yang menutup kata, ketika cerita masih dalam lamunan

Yang meringis, bahkan sebelum gulung ombak mengikis

Yang hening berdiri, tepat di balik cermin menatap mata panjang dalam diam

Yang menangis, walau bibir menyungging senyum menawan

Langkah kaki tidak selamanya bisa terus terambil, ragu adalah niscaya

Layaknya harapan yang datang dan pergi serupa siang dan malam, fajar dan senja

Kedua kakimu hilang pijakan, tak lagi mau membawamu pergi jauh

Kadang, hatimu meminta berhenti; cukup. Sampai di sini saja, katanya

Karena lelah bukan lagi kata yang cukup untuk perasaan yang memenuhi relung dada

Aku tahu kamu ingin berhenti; di titik yang tidak ada nestapa dan lelah payah selanjutnya

Aku tahu kamu memilih cukup; saatnya kamu menikmati sisa hidup

Tetapi henti kisahmu, tidak akan pernah jadi milikmu untuk menentukan

Mau tak mau, hidupmu akan tetap berlanjut,

Waktu bisa jadi bergerak linear, bisa juga tidak

Kadang bulan berganti tanpa kamu sadari.

Kadang satu fajar menarikmu turut serta, dalam tiap detak jarumnya

Aku

Melihatmu, yang berjalan namun tak mau

Melihatmu, yang terus berusaha meski tak lagi ingin

Melihatmu, yang mempertanyakan kembali mimpi-mimpimu

Melihatmu, yang bertahan, tapi terasa rapuh

Kamu ingin dipercaya, tapi hatimu sendiri meragukan kokoh punggungmu

Kadang...

Kamu ingin berhenti saja, entah bagaimana

Kenapa?

Kamu selalu berkata,

Hidup tak selalu mengajakmu tamasya di bawah langit berbintang,

Hidup tidak selamanya menuju pelangi yang indah

Hidup tak selalu menawarkan terang rembulan di dalam pekatnya malam

Hidup tak selalu menyuguhkan cinnamon apple tea kesukaanmu tiap kali kamu pulang, dengan badan lelahmu, atau peach earl grey tart favoritmu

Ketika kamu tidak ingin apa pun selain manis untuk menahan tumpah air mata

Sekalipun hidup membawamu ke hutanーtempat favoritmu selain lautan,

Hidup bisa saja meninggalkanmu sendirian tanpa peta

Kamu merasa cukup lelahnya, cukup pekatnya dalam rimbun pucuk dedalu

Cukup... saja

Aku akan selalu mengingatkanmu pada banyak orang-orang hebat di luar sana

Mereka, yang terus bergerak meski hidup terus mencemoohnya

Mereka, yang meski usaha tidak pernah menjamin bagaimana hidup memperlakukannya

Mereka, yang tetap berjalan. meski bahu kecilnya perih menanggung hidupnya

Mereka, yang selalu tersenyum bahagia

Kamu?

Katamu... kamu ragu,

Pada dirimu sendiri, apakah terus patuh atau berkhianat nantinya

Pada sejuta kemungkinan yang tidak pernah pasti

Pada ketiadaan kemungkinan yang bisa kamu pilih. ketakutanmu mengalahkan keinginanmu

Pada relung kabut didepan sana

Ketakutan-ketakutanmu yang tidak pernah bisa kamu utarakan,

yang terus berbisik tanpa bisa kamu hentikan

Ketakutan itu terus tumbuh bersamamu, di sepanjang waktu

Apa yang kamu takutkan?

Kamu bergeming, lalu menggeleng.

Kutanya, kenapa?

Kamu bilang, terlalu banyak yang kamu takutkan sepanjang perjalananmu

Tapi ketakutan tentang dirimu, adalah ketakutanmu yang paling besar

Kenapa?

Tangismu pecah.

Aku berhenti bertanya, aku ingin menyentuh bahumu, lalu mendekapmu erat

Tapi kamu terlanjur berbalik, aku melihat punggungmu bergerak menjauh

Padahal sebelumnya kamu berdiri mengamatiku lama sekali,

Di depan cermin seolah kita sahabat lama

Kupikir kamu percaya padaku. untuk menceritakan ketakutanmu

Sebab aku adalah bagianmu; pojok kosong hatimu yang terus berbisik agar kamu tetap bertahan

Dariku untukmu, bayang dibalik cermin itu

Gubahan dari langkah diantara peron Stasiun Sendai

Terimakasih

In this video, we will tell you a very brief review of our research progress in the last two weeks.

First, after further discussion with our professor of fisheries and field experts, we are finally done with the design of the new model and scheme for the next research. In this research, we are using catfish as our subject. We separated the subjects into three tanks that have different heights. Our goal in this experiment is to collect more real information of the ideal depth for MINO and to compare it with the existing concepts and theories, because multiple testing with different subjects and variables are very necessary before we embark into the production stage.

Secondly, we have started the small manufacturing process of this research. As the variables of this research are little bit different with our previous research, we had to tinker our design, thus re-measurement and re-calculation had to be done so the product would fit with our research design. This process has been supported by Mechanical technology Laboratory, Gadjah Mada University.

Third, in cooperation with the department of fisheries gadjah Mada University and local catfish famers, we started the installation process of Mino. Started from the base, we assembled the pipe, connected all the joints and set the electronic series to make the water pump on.

Lastly, we did final check on the system and will maintain the quality control. As for the data collection and interpretation, just like the previous research, we will be supported by chemical engineering department and fisheries department of Gadjah Mada University.

For further development, we will prepare the tools and equipment that is necessary for the field application of Mino. As for the mass production plan, we will try to engage closely with local manufacturers in Yogyakarta. In the end, this project would be able to create a bigger ripple effect by benefiting many stakeholders; in this case, we hope we will not only help the fish farmers to have a better livelihood, but also the local business.

We also have started to discuss closely with our mentor. In the last 10th of Augustus, one of our team went to USAID office in Jakarta to brainstorm and discus directly with our mentor, Mrs. Celly Catharina, a Marine Program Specialist for USAID.

For the next two weeks, we will continue the catfish experiment, preparing for the next development of Mino and to improve the product so it could be more sustainable.

Behind the story:

Alhamdulilah semuanya lancar *enggak seru banget ya hehe

I was the one who went to USAID office in Jakarta in that Video hehe. But, i was afraid to add some pictures in this video wkwk. Privacy you know.

My first comment when i went to USAID was one: Maximum security, as American ways.

We must have appointment before go to the office *iyalah wkwk. But, i mean the real printed appointment. The security have list who will come and have an appointment in that day. I have checked in the front my belongings, purposes, etc before i went to parking area. When i thought its done, i was wrong. They were two more checkpoint inside. Alhamdulillah I was not asked and interrogated.

Finally i met with my mentor and discussed a lot hehe. Then i must go to the JCC to attend opening ceremony of Indonesia International Geothermal Conference and Exhibition 2016.
